This was easy. I fried some sliced sausages in butter and olive oil till barely browned and then set them aside on a paper towel. Add sliced onions and peppers and cook them a little. Add garlic and chopped cabbage and toss to coat with the butter and oil, adding more if needed. Put the sausage slices back in, add a couple tablespoons or so of soy sauce, toss, and cover. Let it go for 15 or 20 minutes, stirring a time or two. Ideally the cabbage will caramelize a little but you should cook it to suit.
